Abstract: The invention achieves a mechanical device for pulling seedling plants from the ground in greenhouses and for conveying them by conveyor to a collection receptacle for grading the more mature or better quality plants. Essentially the invention includes an inclined conveyor formed by a pair loop belts, each belt travelling between an idler pulley and a drive wheel, such that the loop belts, being composed of a resilient material such as sponge rubber, are placed in an abutting juxtaposed position to thereby co-operatively form the mechanism which pulls the plant from the ground and as well conveys the plant from the ground toward the collection receptacle.
